Service bulletin RCA-78-22-001-1
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Rivian is initiating a customer satisfaction campaign for some model year 2022 R1T vehicles that may experience a rear wheel liner wire harness (electronic parking brake and wheel speed sensor) pulling out of the harness holder during full wheel droop, allowing the harness to be out of position and contact the inside of the wheel. If the harness rubs through it could cause a loss of electronic parking brake and/or wheel speed sensor for that wheel. This could result in decreased parking brake performance. This condition was discovered after the off-road portion of a media event. The customer will receive adequate forewarning of this condition from the malfunction indicator lamp (MIL). Further, the vehicle will go into a limited performance mode and the electronic parking brake for the other wheel would still be able to hold a steep grade (20%) at GVWR. Installing cable ties will secure the rear wheel harnesses to the knuckle bracket to ensure retention. Rivian is launching this campaign for customer satisfaction and for the continuous improvement of Rivian vehicles.

| RCA-14-22-002-1 | 2022-07-07. Service bulletin. Rivian is initiating a customer satisfaction campaign for some model year 2022 R1T vehicles that may have been built with a low clearance condition between the front wheel speed sensor wire harness and the front dust shield. If the wheel speed sensor touches the front dust shield and this condition persists over time, the vehicle may experience a rub-through of the wires in the wheel speed sensor wire harness. The potential rub-through condition may cause the vehicle to enter into a reduced performance safe-state mode and a fault indicator light will illuminate on the driver display alerting the driver to have service performed on their vehicle. Rivian will inspect and, if necessary, reroute the harness or replace the wheel speed sensor to correct the condition. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles. |
